Dream Chaser: The Return of the Spaceplane

We’re back at Space Symposium for a conversation with SNC’s Mark Sirangelo, leader of that company’s effort to build the Dream Chaser. We’ll also hear a few moments of Bill Nye’s session at the annual gathering as he hosted Bernard Foing and Amy Mainzer. Emily lets us sample her “What’s Up in the Solar System” May roundup. Bruce Betts helps Mat Kaplan feel better about missing the transit of Mercury.
